STM32 MCUs Motor control

In the __weak int16_t STC_CalcTorqueReference(SpeednTorqCtrl_Handle_t *pHandle) function The original ST code contains the below line code.hMeasuredSpeed = SPD_GetAvrgMecSpeedUnit(pHandle->SPD);hError = hTargetSpeed - hMeasuredSpeed;hTorqueReference = PI_Controller(pHandle->PISpeed, (int32_t)hError);I modified the first line of code tohMeasuredSpeed = -SPD_GetAvrgMecSpeedUnit(pHandle->SPD); i put a negative sign before the function.This i have done since the error was never going to 0. Is it correct or i need to remove the negative sign? I have start up issues is it because of this?  

Hi， I'm working with an Maxon 3-phase 1-pole BLDC motor, following is it's motor data table or attached file. the colum with red rectangle is the motor type we're now dealing with.I wondering how can we get the B-EMF constant in the MC workbench electrical parameters from this motor data.And what's the speed constant related with B-emf constant. isn't it b-emf constant reciprocal ？ The motor controller we use is B-G431B-ESC1 Discoery kit, would that board sufficent to driving this maxon motor?We also try to use the motor profiler to get the motor parameters,but the progress bar always stay at 7% or 14% and giving us the max speed setting warning.Looking forward to your feedback, Thank you!Regards!

Hello, Am using in stm32g030f6p6 controller. I just control the bldc fan motor with DRV10983 driver IC. so i new to this driver IC. How to communicate with stm32g030f6p6 to DRV10983 Driver IC with motor. I have using code generate for CubeMx software. And i send the motor command data for i2c communication in MCU to Driver IC. But IC does not give the any response. so i need a help for us.

I would like to have precise, slow motion control of a BLDC motor from a hoverboard.  This 1 minute video shows it well:  https://www.youtube.com/watch?v=JMXz5tzpq7UWould a "STEVAL-SPIN3202" do this?Many thanksMarc

Hi,these days you released STM32 Motor Control Software Development Kit (MCSDK) 6.1 which offers the possibility to create custom boards. The sample boards are very complex and the code is very long. I'm looking for documentation how to write a custom board and how to write the code. Is there maybe a solution to generate the board code?Thanks,Florian

Is there any user guide regarding custom board creation in MC workbench 6.1.0? I can start from the X-NUCLEO-IHM05M1 board, but I have to change the HALL sensor input from TIM2 to TIM3.

I am using EVSPIN32F0601S1 kit. now i want to read the adc channel 5 value. current amplified single given to adc channel 5(IN5) in my kit. i want to read the value of that adc channel. how can i read adc value ?

Dear sir, We are working on one of our pharma project in which we want to drive a hall-sensored BLDC motor  using x-nucleo-ihm08m1 board. So we've downloaded firmware provided by ST microelectronics (STM32CubeExpansion_SPN8_V1.0.2) in which we are loading KEIL code on the board.  The value of global variable showing in the watch window shows error i.e cannot evaluatePlease let us know what the problem is and reply to me as soon as possible.Please find out the attachment below.

Hello,Im new to this and im stuck on 2 things i generated a code from the motorcontrol workbench and im using a Nucleo 64 f030R8 with a IHM07M1A BLDC Motor controller. i can start the motor and control speed. 1st question : where can i change direction because the motor is rotating always the same direction CCW and i also want the motor to turn CW.2nd question : i needed to insert the motor parameters in the workbench but cant find these back in the IDE software maybe someone knows where to find this.Thank you in advance for your assistance. I look forward to receiving your response.

Why doee not STM32 MCSDK(ST MotorContol Workbenc) support Nucleo-F302R8 Control board with 6Step algorithm of BLDC Motor driver? How can I implement 6Step algorithm of BLDC Motor driver on Nucleo-F302R7 Control board？

 Hi,1. Project Purpose:  Generate pulse to control stepper Driver. 2. My method and step:  1) every 2 milisecond calculate out the pulse need to send next cycle;  2) DMA and Timer Handle the pulse sending.      a. Timer update interru  3pte cycle is 2ms,  ARR = 56000.      b. enable OC compare output , Toggle mode      C. Timer count from 0~56000, CCRx will be a series value attempt to toggle the output.          For example, I want to generate 2 pulse in 2ms cycle, Then I need to set CCRx to  14000 , 28000, 42000, 55999 step by step.       d. Using DMA to Send CCRx Array.       e. Using DMA Double Buffer mode. 3. My Question:    1)  All work right when the pulse frequence below 100kHz    2)  It seems that above 100KHz, DMA will be too slow to push the newer CCRx value to the peripherial. So th

This is for a project. I develop a drwaing machine, 2 axis -> 2 steppers for x-y coordinates.

[VERSION]: MCSDK 6.2.0，STM32CubeMX 6.9.2[TOOL]: MotorControl Workbench 6.2.0[DETAILS]: I want to add my custom control board,but it say "Unable to generate ioc file due to: The following has evaluated to null or missing".My custom control board is STM32F405RGT6, but my attempt failed. Then I try STM32F401RDTx, it is same.1.create mcu json (STM32F401RDTx), copy from STM32F401RETx.json.I have to add an MCU that is not in the list, otherwise my custom control board will not be displayed correctly.   Then in this STM32F401RDTx.json file, I replace "STM32F401RETx"  with "STM32F401RDTx" , and change the flash size to "flash" : 384.  The two are just different in flash size, I think it works fine.2.Create new board using Board Manager.  Clone from NUCLEO-F401RE.Then change the mcu name.3.Create new projectSTM32F401RD+IHM17M1Then generate the project. I want to know how to solve this problem.

HiI need to evaluate the ST Motor Control Kit STEVAL-CTM010V1 with ST Motor Profiler GUI Tool v5.4.8.But my board is not listed in the supported boards list. Can anyone please tell me if there is any way I can use the Motor Profiler tool with my Board.Although I can easily select the board in the Motor Control Workbench GUI v5.4.8 and it shows the block diagram with all configurations. ThanksManish

When I try to set all details into the Motor Control Workbench (with Hall Sensors) at Motor Parameters, there are fields for Inertia and Friction, that I am not sure how to configure.The motor spec is as below images.  What should I set for Inertia and Friction.Inertia:      uN*m*s2Friction:     uN*m*sMany thanks,Tom

Hi Team！ I would like to consider a gimbal with STEVAL-GMBL02V1 dev-kit.I would like to change the firmware and verify it, but only a hex format firmware is available. Is it possible to obtain the C/C++ source code?  

 Keep inserting if ( TIMx == TIM1 ) { /* TIM1 Counter Clock stopped when the core is halted */ LL_DBGMCU_APB2_GRP1_FreezePeriph( LL_DBGMCU_APB2_GRP1_TIM1_STOP ); } else { /* TIM8 Counter Clock stopped when the core is halted */ LL_DBGMCU_APB2_GRP1_FreezePeriph( LL_DBGMCU_APB2_GRP1_TIM8_STOP ); } if ( OPAMPParams != NULL ) { LL_OPAMP_Enable( OPAMPParams->OPAMPx_1 ); LL_OPAMP_Enable( OPAMPParams->OPAMPx_2 ); }but  LL_DBGMCU_APB2_GRP1_TIM8_STOP doesn't exist. Every time I "generate" code i have to go in an comment out this line since I don't have a TM8 thus in stm32f302xc.h #define DBGMCU_APB2_FZ_DBG_TIM1_STOP isn't present. Someone at STM Please LMK how to prevent MX from generating this?

I'm using custom firmware on EVSPING4 board.After MC_StartMotor1() motor and ABI encoder is aligning, and everything works as expected.After that I'm using MC_StopMotor1() command to stop motor and moving motor by hand.After that I'm using MC_StartMotor1(), and It looks like motor working little worst. I don't want realign encoder again.It's strange because ENCODER_M1->TIMx->CNT looks working.I was reading ENC_CalcAngle(), and hElAngle (responsible by commutation) is calculated from hMecAngle, and hMecAngle is calculated from ENCODER_M1->TIMx->CNT.What I'm doing wrong?[VERSION]: MCSDK 5.4.8

Hello I am trying to use the new X-CUBE-MCSDK 6.1 but can not find the STEVAL-ESC001V1 device in the listed power or control section when I am trying to start a new project. Is this device not supported or am I missing something?Thanks

I want to use the flux weakening in my project using Workbench 6.2 i generated the code using the below settingwhen i select the speed control mode i can see the tab to select the Flux Weakening regulator.But when i select the torque control mode The tab for the flux weakening regulator does not appear. I know the flux weakening regulator is used to increase speed. The code for flux weakening does not generate in Torque control mode. So can i use the flux weakening code in torque control mode or not? Can i use the negative Id to increase the speed limit. My idea is a. generate the code for flux weakening using the speed control mode.b. integrate the code.c. Use the torque control mode and give negative Id.Does it work like this? Please help.

I try implementing FOC for Bull Running BLDC motor with F302R8 Nucleo board and IHM07MI expansion board.Help me in this regard. 

Hi,We used X-NUCLEO-IHM12A1 to run a single DC Motor which was connected to A+ and A- pins.The Vref voltage for the motor driver can be set to maximum of 0.5V as per the datasheet. The motor stall current  for our motor as per the datasheet is 370mA.So, as per calculation, Voltage across Sense = Current through the motor * Sense Resistance= 370m * (0.68 || 0.68) = 370m * 0.34 = 0.1258. But the set Vref is 0.2V, the motor stopped in between. Further the Vref value was increased to 0.5V still the problem exists. There was no Fault led indications also. The motor stopped rotating in between. What might be the possible causes for the behavior?Will the motor driver stop the motor without triggering the Fault led?
